A study of Spanish attitudes regarding the custody and use of forensic DNA databases.

One of the issues that has resulted in much disagreement in many countries at different levels concerns the kind of institution that should be given the responsibility of exercising custody over biological samples and the DNA profiles obtained from these samples. In the field of forensic genetics, there is no doubt that the existence of DNA criminal databases benefits the control and investigation of crime. However, certain criticism, supported to a great extent by the particular vision of genetic exceptionalism has been aimed at the ethical and social consequences resulting from the inappropriate use of such databases.

Y-chromosome STR haplotypes in two population samples: Azores Islands and Central Portugal.

The Y-chromosome haplotypes defined by nine STRs (DYS19, DYS385, DYS389I, DYS389II, DYS390, DYS391, DYS392 and DYS393) were studied in 207 unrelated individuals from Central Portugal and 63 from Azores Islands. The most common haplotype in Central Portugal was shared by 3.4% of the males, while 160 haplotypes were unique.

Y-chromosome STR haplotypes in a southwest Spain population sample.

The Y-chromosome polymorphism of eight STRs (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392; DYS393, DYS385) were studied in 111 unrelated individuals from the population of southwest Spain. The most common haplotype was shared by 3.6% of the sample, while 99 haplotypes were unique.
